Chapter 12, Problem 11E

a.

Program Plan Intro

Given:

File size = 1024 bytes

Payload size = 128 bytes

Systems are running IPv4.

We know that:

Size of TCP header = 20 bytes

Size of IP header = 20 bytes

Total size = 40 bytes overhead per segment

The file size can be divided into 8 segments each segment contains 128 bytes. So (40 + 128) × 8 = 1344 bytes .

So totally 1344 bytes will be sent by 8 segments.

b.

Program Plan Intro

Given:

File size = 1024 bytes

Payload size = 128 bytes

Systems are running IPv6.

We know that:

Size of TCP header = 20 bytes

Fixed length of IPv6 = 40 bytes

Total size = 60 bytes overhead per segment

The file size can be divided into 8 segments each segment contains 128 bytes. So (60 + 128) × 8 = 1504 bytes.

So totally 1504 bytes will be sent by 8 segments.

Homework You have the row vector (A) that has values from (-100 to 100), write MATLAB codes to: (1) Interchange the first 10 elements with last ten elements. (2) Replace the elements at indices (93,9,17,50) of A with 99. (3) Return the second element and the element before the last of A as a column vector (C1). (4) Extract the first five elements and the last five elements of A and append them as a row vector (R). (5) Set the elements of A with odd indices to zeros(0).

When the FCC added Color Television to the Industry Standards, they went with the system developed in the 1940s by Peter Goldman for CBS.   Question 15 options:   True   False Part of the reason that many critics disliked 1950s gameshows was the fact that gameshows offered one of the few opportunities to see unscripted interactions with "real" (average/non-famous) people on television.   Question 16 options:   True   False The Andy Griffith Show is an example of the "rural revival" shows that become enormously popular on 1960s American television.   Question 19 options:   True   False During the Network Era, the hours before primetime each day were exclusively devoted to locally-produced programming, not programming dictated by an affiliate station's parent network.   Question 20 options:   True   False
